<p>An auto-focusing image processing system for synthetic aperture radar (SAR) is disclosed wherein an image is reproduced from received SAR data through range compression, range curvature compensation and azimuth compression using a range reference function, a range curvature compensation function and an azimuth reference function, respectively; according to the invention, the azimuth compressed signal is divided into a plurality of look components, a correlation coefficient between the signals of selected two look components is established, the image shift amount K between the two look components giving the maximum correlation coefficient is determined, and said shift amount is used for generating said azimuth reference and range curvature compensation functions. This system is able to reproduce well-focused and high-quality images. </p> |
